摘要：
一名 68 岁男性，间歇性不明原因发烧 5 个月，接受 18F-FDG PET/CT 检查致病病变。左侧骨盆髂血管区域发现 18F-FDG 强烈病变，高度提示恶性肿瘤。一个半月后，通过 CT 血管造影发现了一个巨大的左髂内动脉瘤，对应于 18F-FDG 强烈的病变。结合炎症标志物升高，最终诊断为炎性髂内动脉瘤。还发现了 18F-FDG 摄取量低的腹主动脉瘤。版权所有 © 2023 Wolters Kluwer Health, Inc. 保留所有权利。
A 68-year-old man with intermittent fever of unknown origin for 5 months underwent 18F-FDG PET/CT to detect causative lesion. An 18F-FDG-avid lesion was revealed in the left pelvic iliac vessel region and was highly suggestive of malignancy. One and a half months later, a giant left internal iliac artery aneurysm was identified by CT angiography, corresponding to the 18F-FDG-avid lesion. Combined with elevated inflammatory markers, he was finally diagnosed as having inflammatory internal iliac artery aneurysm. An abdominal aortic aneurysm with low 18F-FDG uptake was also identified.Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
